Ego-C Twist 1000mAh charge time?

[Beachbabealways]

I have tried to find this info but not having any luck.

When I first got my Twist I charged it up which took 2 hours and got the green light on the charger. (I think it comes partially charged?)

So the next day it needed to be recharged. I put it on the charger (usb to wall adapter, same as I did before) but this time 10 hours goes by and the light is still red and every few seconds blinks green back to red. So I took it from the wall and inserted it into my laptop. Two hours go by still no change. Hopefully it is just the charger.

The place I bought it from is sending me a new usb/wall adapter.
I have had it for 6 days which includes today.

So can some please tell me (in your experiance) how long it takes to charge the 1000mAh battery?

The ego USB charger says: Input: DC 5V 500 mA Output: DC 4.2V 420mA

The wall adapter says: Input: AC 220V-50/60HZ 150mA Output: DC5V=500mA

Thanks for any and all help.

My 900mah twist battery's take about 2.5-3 hours to charge from dead. 10 hours is way to long for a 420ma charger. You could try cleaning the contacts on the charger and battery but it sounds like either the battery or the charger is not working correctly.

I use 1k mah Twists and when they're totally depleted they take @ 3hrs to charge in my experience. Hopefully you just got a dud charger and it's not your battery. When you can I'd order a back up charger in the future just in case. I have two chargers, two wall adapters, a few 1k mah Twist batteries and some regular 650mah egos in a drawer....just in case. Back ups for your back ups is a good way to go.

Wow, I knew that was to long. I contacted the company I bought the set from the day after it arrived however it was late at night.
Finally TODAY they agreed to send me a new charger. I wasn't to happy that it took that long. The girl asked me to try charging it via an alternate source (phone) which left me scratching my head. I don't have that capability. Is that even possible?

What she was suggesting was that instead of plugging the charger into the wall adapter, plug it into a USB port on a computer or something else. That way, if it charges normally, then it's the wall attachment that is the problem. I personally wouldn't do it. If I was sure it wasn't the battery (which is obvious if the problem occurs with different batteries), I'd just order another wall charger (or more likely another starter set since the price difference would be like getting a charger with discount batteries).

Anyway, just my experience, but I've had the exact problem you describe twice and it was the battery both times.

I just had my own issues with my first Twist the other night, I found it only charged for like..five or ten minutes before going green and it was still dead or close to it.. What I ended up doing was popping it off the charger (standard eGo 420) and turning the voltage setting on the Twist all the way to the maximum before hooking it back up. Took maybe three or four hours off my PC's USB port but it fully charged and is still going strong. I swear I saw a post on setting the voltage higher on it for charging but I've not been able to find it again so maybe I'm imagining it. Charger works perfect with my other eGos, and the Twist works fine as near as I can tell as well, lasts the expected time between charges, just had to be turned up to get a full charge. May be something to try. Got spare chargers in the mail right now and looking for an eGo-C Upgrade with passthrough as a home-use battery, so I'm not burning through 'em all the time.

ETA: It's one of the larger Twists, don't know the mAh rating as I traded a guy for it, but I believe it's 900 or 1000mAh, genuine Joyetech, so whatever the largest capacity they sell..it's way too long to be a 650.

I got a reply from the CS Rep and they said this for the charge time for the 1000mAh ego-c Twist:

You're very welcome. It takes about 6-7 hours to charge a 1000mAh battery.

I do plan on buying another set for backup.

 

[Snicks]

I charge mine every night before I hit the sack. I usually get up around 6 hours later and my 1000mah is ready to go.

 

[debcartee]

I don't think you are imagining it, Kellycat I saw it too. When I charge my twist I turn it all the way to 4.8 and charge it for about 5 hours.

Simple: You have the wrong AC to USB adapter. That is a 220v European model. At 120 volts it isn't designed to provide the DC output current needed to correctly charge an eGo.

Where did you buy this from? You aren't the first person getting an incorrect AC adapter in recent reports.

When you first get your battery it should arrive at least partially charged. That would explain why the charger appeared to work the first time. Right now just use your computer USB port until a correct adapter shows up. The specs on your eGo charger dongle itself are correct.

mine gets fully charged in about 3 hours.

Some dual-voltage wall warts will only show specs for 220v on them I have a few from reputable name-brand companies for phones/etc that only show their maximum ratings, which are 220v@whatever amperage, yet they work on 110v outlets at the same amps just fine, tested with a variety of meters and devices. With the increase in 'universal' AC devices for travelers, it takes up less space only printing the maximum ratings, and assures people they can use them with those plug adapters for traveling in the UK/Euro/Aus/etc.

Have you ever opened up one of these cheap AC/USB adapters that come with eGo charger dongles? That is so not what's going on here. They are only designed to produce one output voltage-ish, based on one input voltage. Got the wrong coil in there for a 220v model and you don't get the correct voltage or output current at 120v. The construction is actually quite frightening on any I have cracked open.

My 1000s take 10+ hours to fully charge from dead.

If you look closely you answered it yourself (well that is if you had education on batteries...were here to help in that edumication )

Charger pushes 420mA an HOUR..you battery is capable of holding 1000mAHOURS thus it "should" take around 2.5 hrs...but since no battery is 100% efficient at changing electrical energy into "chemically stored" energy it takes a bit longer so maybe around 3 hrs

all the mA vs mAh is milliamps x hours...it just gives a "time" variable to battery capacity

If you are given the current capacity of a battery (in mAH), dividing this number by the current requirement of the circuit will give you the time of the battery will last under a constant load.

Let’s take, for example, a 9.6 volt battery rated at 1500 mAH (milliampere-hours) at 250 milliamps. By dividing 1500 mAh by 250 mA, we find the battery will discharge in about six hours.

1500 mAh ÷ 250 mA = 6 hours

In contrast, the battery might be rated at 1250 mAh if used in a circuit requiring 500 mA. In this case, the battery would discharge in about 2.5 hours.

1250 mAh ÷ 500 mA = 2.5 hours

It is this concept that makes predicting the usable time of camcorder batteries difficult. Camcorders require a great deal of current, especially when using certain features, such as auto-focusing, fast forward, or rewind. Each of these features requires a different amount of current. This factor alone makes the usable time difficult to predict. However, other factors must be taken into consideration, such as temperature. Therefore, a 2000 mAh battery will not necessarily last twice as long as a 1000 mAh battery -- although it will typically be close.

Li Ion batteries MUST charge at 4.2vdc, otherwise it reduces the charge capacity level and the life of the batteries

You sure you don't have one of the 120mA chargers??

Wow, that's a long time, I have 4 or 5 twists 1000mah (backups for my backups) and I use them until the light flashes and they won't vape anymore. I don't think it has ever taken any of them that long to charge.... I haven't timed them but maybe 4 - 5 hours on the standard Joyetech charger.

 

[ZNinja]

Output shows to be 420mA. I have gotten to where I switch batteries when I get home from work even though I have several hours of vape time left. Put the first on the charge at 6pm and the other when I go to bed at around midnight. Otherwise they are not both fully charged when I get up at 7am.

Better to NOT drain them all the way....use them, if you have fresh (fully charged) spares...pop the used one on the charger, you will get more charge cycles out of the battery that way

Ah, fair enough. To answer your question I have not opened any of the 'bare-bones' Chinese chargers for this stuff, the only wall-warts I buy are genuine, name-brand gear from cellular supply shops, or other reputable electronics dealers. Far too worried about what I'd find in a cheap one after seeing posts on some of the tech blogs I frequent, people having shoddy Chinese wall-warts that catch fire and all sorts of other nasty things because they lack basic safety features like voltage regulation, rectifiers, al etc. I've seen some that are just a couple diodes, some big caps, and a resistor to turn 120vAC into 5vDC..no idea how they even work at all to be honest at that point, seems like they'd just explode as soon as you plugged them up more often than not.

ETA: The reason for my original post is that the OP stated their charger had '50/60HZ' printed on it, Euro 220v doesn't run at 60hz, only American 110v does as far as I'm aware, and potentially Japan/Canada/others that use 110v, but I believe even some of those cycle at 50hz. I know our powerlines are standardized at 60hz because old clocks would 'cheat' and use that cycling to keep accurate time, one phase-shift equaled one second.
